Prevent data loss on missing order keys

[gschier]

Here is an example of how data loss can occur on missing keys. It would be nice if the "failure" condition favored keeping data instead of skipping it 🙂

const obj = {
  users: [
    { name: 'Tom', id: 1 },
    { name: 'Jane', id: 2 },
  ],
};

const order = {
  '$': ['users'],
  '$.users.0': ['id', 'name'],
};

const result = orderedJSON.order(obj, order);

// result is missing the second user
//
// {
//   users: [{
//     id: 1,
//     name: 'Tom',
//   }],
// }
